Thickness of Aquifer from Impermeable Layer given Modified Drawdown in Well 2 Solution

STEP 0: Pre-Calculation Summary

Formula Used

Unconfined Aquifer Thickness = ((Drawdown in Well 2)^2/(2*(Drawdown in Well 2-Modified Drawdown 2)))
H_ui = ((s₂)^2/(2*(s₂-s2^')))
This formula uses 3 Variables

Variables Used

Unconfined Aquifer Thickness - (Measured in Meter) - Unconfined Aquifer Thickness is the aquifer thickness at initial stage before pumping.
Drawdown in Well 2 - (Measured in Meter) - Drawdown in Well 2 is a peak-to-trough decline during a specific period for well 2.
Modified Drawdown 2 - (Measured in Meter) - Modified Drawdown 2 is the modified value of drawdown for well 2.

STEP 1: Convert Input(s) to Base Unit

Drawdown in Well 2: 2.136 Meter --> 2.136 Meter No Conversion Required
Modified Drawdown 2: 1.714 Meter --> 1.714 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

H_ui = ((s₂)^2/(2*(s₂-s2^'))) --> ((2.136)^2/(2*(2.136-1.714)))

Evaluating ... ...

H_ui = 5.4058009478673

STEP 3: Convert Result to Output's Unit

5.4058009478673 Meter --> No Conversion Required

FINAL ANSWER

5.4058009478673 ≈ 5.405801 Meter <-- Unconfined Aquifer Thickness
